Four-letter abbreviations are used as a compromise between clarity and brevity. While longer captions are easier to understand, please review results in a variety of browsers and on a variety of monitors before substantially lengthening them.
(1) The leftmost column is organized by system. Many of the colors reflect long-established standards for anatomic labeling; some are internal to Wikipedia. (For infectious diseases, secondary colors are as defined at Wikipedia:Taxobox_usage#Color). The "M" column is used to provide links to this page.
(2) The second column includes information on anatomy, and other fundamental, preclinical information that is necessary for the understanding of a system.
(3) The third column includes conditions. The organization follows ICD to the greatest extent possible, and explicitly splits out tumors ("tumr"), congenital conditions ("cong"), and symptoms/signs ("sysi"), with the remainder labeled here as "noco" for "noncongenital". In some cases these divisions are somewhat ambiguous. Symptoms and signs are classified superficially in ICD. The eponymous signs ("epon") are not in ICD, but follow ICD classification as closely as possible. However, some eponymous signs require intervention to be observed, and could be considered procedures. Although the term "neoplasia" in some cases may be preferable to "tumor", the latter term is used here to provide a more comprehensible abbreviation.
(4) The fourth column is for responses to a condition: medications administered, tests performed, surgeries, and other interventions.
